DataThief III is a program to extract (reverse engineer) data points from a graph. The resulting plots show material combinations. Furthermore, some support documentation is badly needed. Graphs are great for understanding results in reports and papers. I would suggest however (please add it to my wish list) to control the Automatic curve detection (that is tolerance, spacing, and the total number of points) directly in the main frame, and not to hide it in the references.

We can only hope this nice application will not be swallowed by a bigger company, like another succesful apllication (Curvus Pro X) by the same company (Arizona). It works beautifully,and the list of points produced is easily recognized by (say) Kaleidagraph for further treatment. My first impression from this application is fantastic. Suddenly, out of the blues, here comes this masterpiece GraphClick to fill up the vacuum. I was desperately waiting for its analytic continuation into OSX, but as many others, had to face the fact that it was discontinued. Once upon a time, at those glorious days of OS9, there was a cute little application called DataThief by Kees Huyser and Jan van der Laan.

GraphClick is a graph digitizer software which allows to automatically retrieve the original (x,y)-data from a scanned graph, a chart or a movie. In my opinion, the quickest way to digitize the graph is through 'Grabit' which is one of the applications of MATLAB. Good, the data are points can be isolated via color recognition.Note: GraphClick is not being sold anymore and is listed only for people who had purchased it in the past. I clicked on the Settings tab, fiddled with some options, and got the next graph via the Show button. I am interested in automating this process for a graph with hundreds of data points? Drag the crosshairs from the gray box over each data point. Let's match the data points via the scatter plot option (lower right button). Tracing a continuous graph appears to be just one (the upper right button) of DataThief's four data acquisition modes.

The result was a tidy text file with my data points. Zhou, Y., Tan, C.L.: Hough-based model for recognizing bar charts in document images. I placed the Start, Color, and End markers, choose Trace (Action Menu), and then Export (File Menu). DataThief III is usually a program to acquire (change professional).

The vertical red/green rectangle is a progress bar relating how fit, squared, orthogonal the reference points are. Graphclick Free Of ChargeGraphClick is usually a chart digitizer shareware for Mac. Next, I set the coordinates of some reference points on the graph, by moving the colored crosshairs. For points, WebPlotDigitizer has the blob detection algorithm that can locate the centroid of blobs of colour, indicated by the colour option. DataThief III is a Java application to extract (reverse engineer) data points from a graph. With PlotDigitizer, you can extract data from XY, bar (horizontal), bar/column.

It is a native Mac OS X application and an Apple design award winner. The best alternative to Datathief, a data extraction tool from graphs. I found it helpful to zoom in (Action Menu). DataThief can trace lines, but does not have the ability to pick out points in a point graph without the user specifically pointing to where the points are. GraphClick is a graph digitizer software which allows to automatically retrieve the original (x,y)-data from the image of a scanned graph or from a QuickTime movie. After a plane is defined (by marking three coordinates on the picture), one can mouse over the graph to find the numerical coordinates of each points.Ĭan it be automated? Online documentation seems to be nil. DataThief is a nifty Shareware utility for extracting the coordinates from an image of a graph.
